Brilliant Ted Talk !! Defines a HUGE problem that has snuck up on our society while we have been sleeping !
The problem is that too much personalization from all of our favorite web companies, in essence is a form of digital censorship. If google and facebook etc show you only what you "like" then how are you supposed to get the real news ? or get informed on topics that are uncomfortable, but necessary ?
Of course, we at XO, are hard at work in the lab working on a solution that will prevent filter bubbles in web search !
